Remarks. — An internal mould of a right valve from the Upper Greensand of 

 Devizes, which almost certainly belongs to this species, is preserved in the 

 Museum of Practical Geology (No. 6454) ; its length is 28 mm., and its height 

 11 mm. I have seen no other specimen. The hinge is apparently unknown.
